Visions Of Music

While there are numerous histories of album covers (including Album: Classic Sleeve Designs, The Art Of The Album Cover, and Art Record Covers), sheet music design is a relatively niche field of interest. Visions Of Music, by Tony Walas, is a history of sheet music covers.

Despite its subtitle (Sheet Music In The Twentieth Century), the book includes examples from the Victorian era onwards, demonstrating that illustrated sheet music covers existed long before Alex Steinweiss designed the first pictorial record sleeves. The covers in the book are only from the author's collection, though it's the first survey of the subject to feature covers from all genres.
